Sure, at MIT building interactive LED-powered disco dance floors is a good way to decorate your dorm and procrastinate. But, Chris O'Shea of pixelsumo
reminds me, for the designers at Lightspace, it's serious business.
Clearly, the MIT students' DIY project was directly inspired by the
Lightspace team that's . . . wait a minute . . . headquartered in
Cambridge, Massachusetts. Guess there's just something about Cambridge
that makes people want to build elaborate digital disco dance floors.

Lightspace's interactive floors respond in subtle and ingenious ways,
which is why small children are so fond of them. (And, as we've learned
in the past on CDM, small children love heating up dance clubs.)
